Freshwater mussels may be among the most important animals most people have never noticed. Buried beneath riverbeds across North America, they quietly filter enormous volumes of water every day, helping keep rivers healthy for wildlife and people alike. "The Keepers of the River" is a roots reggae tribute to these unsung guardians of clean water and to the conservationists working to restore them. Built on a deep bass groove, bubbling keys, off-beat guitar, horns, and soulful harmonies, the song celebrates the power of small things to make a big difference.
